Problem building with SPNEGO support

[spfma...@e.mail.fr]

Hi,

 

As I still don't understand how to customize webflow, I decided to give a try to mixed mode authentication. Seems to be close from why I am trying to get.

 

So I tried to enable SPNEGO support following the instructions found here : https://apereo.github.io/cas/6.4.x/authentication/SPNEGO-Authentication.html

 

After downloading the latest "jcifs.jar" to "lib/jcifs-ext.jar" at the root of my project (clone of the overlay repo), I added the following two lines in my "build.grade" :

implementation "org.apereo.cas:cas-server-support-spnego-webflow:${project.'cas.version'}"
implementation files("${projectDir}/lib/jcifs-ext.jar")

 

The build phase seems to run correctly, but at runtime I get this blocking exception "java.lang.NoClassDefFoundError: jcifs/spnego/Authentication".

 

If I explode the war, the jar file is present

find . -name jcifs*
./lib/jcifs-ext.jar
./build/app/WEB-INF/lib/jcifs-1.3.17.jar
./build/app/WEB-INF/lib/jcifs-ext.jar

 

I also tried to rebuild after commenting the line including the "jcifs-ext.jar" as it seems there is a jar in the base webapp (though the doc says the opposite) but the result is the same.

 

Is there something else to configure to solve this problem ? Sounds like a classpath missing something, but in this context I don't know where to check or what to add.

 

Regards

Hi again,

 

It seems there was a conflict with between "cifs-1.3.17.jar" provided in the base war and the added "jcifs-ext.jar".

 

Thank to the log4j maelstrom, I was able to find the up-to-date syntax to exclude a JAR from the build process  :

 

    configurations.implementation {
        exclude group: 'jcifs', module: '*'
    }

    implementation "org.apereo.cas:cas-server-support-spnego-webflow:${project.'cas.version'}"
    implementation files("${projectDir}/lib/jcifs-ext.jar")

 

I don't know if it's the right way to do it, but it works !

 

Regards
